When rendering large scenes Vray notifies an error. Here is the text of the warning: Scene bounding is too large, possible raycast errors. When you render everything is fine, but I am concerned about "possible raycast errors", that they may appear later. How to fix this error, than it is fraught and even whether to pay attention to this warning? In order to cause such a warning is enough to create a very large scene.

Hello! If I am not mistaken, in the V-Ray messages, a warning is signified in green, that is not an error, but only a warning. You actually answered his own question by saying that the large size of the scene is the message. And there is. If the size of your scene (Scene bounding - the boundaries of the stage) are very large, such as tens of kilometers, the V-Ray warns that there may be problems with the Raycasting due to the long flight calculation reykastara rays in a huge stage. What Raycasting (ray - luch, casting - throwing) advise to read our tutorial dedicated to this algorithm. As for the warning, you can ignore it for as long as you do not have problems, because it is only possible (possible) will raycast errors, but not necessarily😉

You're right. My scene - it mnogkilometrovy bridge. I came up with something on this subject, and I want to share with you. I scaled the scene in units (and vice versa is possible, on the situation) and thus reduced its size to reykasta, but in practice it has not changed, and no more warnings.

That's right. scene boundaries are calculated in system units, enough to group all the objects in the scene, and their banal to scale using the Select and Scale tool. This will reduce the actual size of the space scenes, that just removes the warning. But in the case of scaling, it is guaranteed to cause problems if you decide to supplement the scene other objects have the correct scale, for example by inserting the car to place it on the bridge. Then the car wheel is greater than the bridge itself😁 So, as I said above, it is easiest to ignore this mesedzh all.

there was such an error, reduce the distance to the sun - it has disappeared
